Abstract

The invention relates to the manufacture of furniture, particularly to joining elements of separate wood parts of the furniture. In order to increase the endurance of the mortise and tenon joint and decorative qualities thereof as well as to simplify the assembling of wood parts of various configurations the mortise and tenon twig joint comprises a curved wood part 1 with tenon 2 and straight wood part 3 with semicircular mortise 4, moreover, both the curved wood part 1 and straight wood part 3 have mutually parallel grain 5 and the configuration of tenon 2 coincides with that of mortise 4. When assembling the joint tenon 2 is inserted into mortise 4. Due to the parallel wood grain 5 of tenon 2 and mortise 4, deformations of the grain 5 in mortise 4 correspond to deformations of the grain 5 in tenon 2. As a result there is no strain of the glue joint, thus the joint does not become loose.

Description

TWIG JOINT FOR FURNITURE

The present invention relates to the manufacture of furniture, particularly to joining elements of separate wood parts of the furniture, which are used for assembling chair, table or other furniture elements.

The art is aware of a joining of wood parts of furniture (US 4042307 A) where a joint is formed by pushing a grooved tenon into a dovetail-shaped mortise containing a barbed wedge such that the wedge is forced into the tenon groove, thereby spreading the tenon to the dovetail shape of the mortise and anchoring the barbs into the tenon, thus securing the joint.

The great disadvantage of the said joining is due to its complexity since the grooved tenon is to be pushed into each mortise as well as the low endurance and insufficient decorative qualities of the joining, thus making it impossible to create a joining of parts of different configurations. The art is also aware of a mortise and tenon joint (EP 0498035 A1) where a corrugated, flat, flexible strip corresponding to the contour of the mortises and tenons is provided whose width is equal to the insertion depth of the mortise and tenon joint and which can be inserted between the mortises and tenons of the joint.

The disadvantage of the said joint is the insufficient endurance, complexity of the joint, besides its construction does not allow assembling small wood parts of different configuration.

There is known in the art a two-member structural joint (US 3879906 A) where one of the members is right angularly dadoed into a slot in an edge of the other member, and in addition is interlocked with the other member by a dovetail type tenon and mortise joint.

The disadvantage of the mentioned joint is insufficient endurance of the joint as well as weak decorative qualities thereof.

The art is aware of a mortise and tenon joint (US 4403886) for assembling three or more components. The mortise receives a pair of opposed tenons with their end surfaces in contact inside the mortise. The tenons are right trapezoidal in contact along their inclined surfaces of equal slope and threaded fasteners secure the assembled joints. The disadvantage of the said joint lies in its low endurance and complicated construction thus not allowing to create decorative joinings of furniture elements.

There are also known in the art furniture constructions (WO 9400700 A1) having at least three flat surfaced members to be joined by mortises and tenons of a cross-sectional size and shape enabling the members to be slidably joined. The resulting joint between the first and second members enables the second member to have two positions of use. In the first position the second member, the third member can be slidably joined to the first member and in the second position the third member is held in place. The great disadvantage of the said joint is insufficient endurance and complexity thereof.

The art is also aware of a mortise and tenon dead joint (RU 2130829). There are two wedge-shaped plates situated in the mortise and two gaps made in the tenon. As the tenon is inserted into the mortise the wedge-shaped plates move into gaps, thus securing the joint.

The disadvantage of the said joint is low endurance, lack of decorative qualities and complicated construction thereof.

The present invention aims to increase the endurance of the mortise and tenon joint and decorative qualities thereof as well as to simplify the assembling of wood parts of various configurations during the manufacture of furniture.

The aim is attained through a twig joint of wood parts of the furniture where the joint consists of a curved wood element with tenon and straight wood element with semicircular mortise, both the curved and straight parts have mutually parallel wood grain, moreover, the configuration of the tenon coincides with that of the mortise. The general idea of the present invention is shown in the accompanying drawings.

Fig. 1 shows a mortise and tenon twig joint;

Fig. 2 shows a traditional mortise and tenon joint;

Fig. 3 and Fig. 4 show various joints of wood elements; Fig. 5 shows a traditional joint secured by curved elements;

Fig. 6 shows how the nature arranges the grain between the stem and the twig. Fig. 5 shows a traditional joint secured by curved elements;

Fig. 6 shows how the nature arranges the grain between the stem and the twig.

According to Fig. 1 the mortise and tenon twig joint comprises a curved wood part 1 with tenon 2 and straight wood part 3 with semicircular mortise 4, moreover, both parts have mutually parallel grain 5.

The present mortise and tenon twig joint is realized in the following way:

Before the assembling tenon 2 of the curved wood part 1 and mortise 4 of the straight wood element 3 is covered with glue. Thereafter tenon 2 is inserted into mortise 4. Due to the parallel wood grain 5 of tenon 2 of the curved wood part 1 and mortise 4 of the straight wood part 3 deformations of the grain 5 in mortise 4 of the straight wood part 3 would correspond to those of the grain 5 in tenon 2 of the curved wood part 1. As a result there is no strain on the glue joint during the shrinking and swelling of the wood, thus joint does not become loose.

Fig.2 shows a traditional mortise 7 and tenon 6 joint. To get a proper joint tenon 6 and mortise 7 are covered with glue, thereafter the tenon 6 is inserted into mortise

7. Due to changes of moisture the mortise 7 of the joint is shrinking and swelling, moreover, the grain of tenon 6 has cross direction. As a result sooner or later the glue would demolish and the joint become loose.

According to the present invention and as shown in Fig. 3 and Fig. 4 it is possible to assemble joints between elements of different configuration, thus allowing very slim and elegant constructions.

As shown in Fig. 5 it is also possible to assemble traditional mortise 9 and curved tenon 8 joint. However, such joints are not solid since the wood grain in mortise 9 and tenon 8 does not fully coincide. The surface contact of the tenon 8 and mortise 9 is too small, thus not allowing the grain of tenon 8 and mortise 9 fully coincide.

Fig. 6 shows how the nature arranges the grain between the stem and the twig, i.e. shows the logic of the natural twig joint.

The present invention allows to create solid joints from multi-layer elements with parallel layers. In such elements there is no strain on the glue joint during the shrinking and swelling of the layers and as a result the joint does not become loose. In accordance with the present invention by making use of the natural qualities of wood grain as well as the qualities of the paralleling plates of the multi-layer elements, both solid and decorative joints for furniture may be created, thus meeting the demands of contemporary customer.
